It's fairly similar to the other MSM8916 devices. The device tree contains initial support for the Xiaomi Redmi 2 with: - UART (untested, probably available via some test points) - eMMC/SD card - Buttons - Vibrator - WiFi/Bluetooth (WCNSS) - USB Note that the Xiaomi Redmi 2 is available in variants with different names (e.g. Redmi 2 Prime, Redmi 2 Pro, ...). As far as I know the main difference between those is the amount of RAM and supported LTE bands. This difference is automatically handled by bootloader/modem firmware so there is no need for separate device trees.
